JOHN S. RUNYAN, OF COLUMBUS, OHIO.

SPECIFICATION forming part of Letters Patent No. 391,339, dated October 16, 1888.

(No model.)

To all whom it may concern.-

Be it known that. I, JOHN S. RUNYAN, a citizen of the United States of America, residing at Columbus, in the county of Franklin and 5 State of Ohio, have invented certain new and useful Improvements in Catch Basins and Traps for Sewers, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvementsiu the construction of sewers and'the approaches to the same from the gutters of the streets.

The object of my invention is to provide a sewer-trap and cover which will admit the 5 water and heavy debris from the street to enter the sewer and at the same time prevent the sewer-gas from escaping into the street.

My invent-ion therefore consists of a sewer top or covering having a spout which will ad mit the water from the gutters, said spout pro jecting some distance into the veri ical portion ofthe sewer-basin, the inner end of said spout being provided with a door whereby the stench and gases are prevented from coming out into the streets.

Referring to the drawings, Figurel isa vertical sectional view of my improved sewer-top basin and sewer. Fig. 2 is a top view, partly in section, of the sewer-basin top and trap. Fig. 3 is a sectional View of a portion ofthe top with the spout and valve or door.

A indicates the basin, which receives the water from the gutters of the street, and is made of masonry or other preferred form of construction. The basin or reservoir A com municates with the sewer B by means of the pipe 0, said pipe entering the basin some distance above the bottom, so as to leave a place into which the dirt and other dbris from the streets will settle and collect, and from which it can be taken through the man-hole in the top of the basin.

D is the top or cover of the basin, which is made of cast-iron or other suitable material, and provided with a man hole, E, through which access is had to the basin. The top D is provided with an annular flauge,a,lo adapt it to rest firmly on the top of the masonry of the basin, and with shoulders or offsets 1), against which the curbstones F abut. One side of the top or cover D is provided with a pocket, G, having an opening, H, which is closed by the swinging door I, said door being hung on the hooks K. The hooks K are of such a form as will allow the door to rise and swing inward in case large bodies should be carried into the pocket G and allow the same to pass into the basin. The pocket G has an inclined bottom,L, which projects some little distance in from the side of the basin, and the door I fits snugly down against the edge of the same. This construction prevents the sewer-gas and offensive odors from coming out into the street, as the door or valve is closed at all times, except when the pressure of water becomes too great in the pocket, when the door will yield and allow the water to pass into the basin. This is an important feature of my invention, as the gases and noxious odors are prevented from passing out to foul the atmosphere in the vicinity of the month of the basin.

What I claim, and desire to secure by Letters Patent, is

In a cover for sewer-basins, the combination of the spout L, with the door or valve I, and hooks K, engaging slots in said door, whereby the door is permitted to rise and allow large bodies to pass into the sewer.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN S. RUNYA'N.
